一种利用动态信息迭加生成用例模型的方法。该方法可以利用多次收集到的动态信息，迭加生成目标系统的用例模型并以UML用例图的形式呈现-An approach to incremental construction of use case model from dynamic information is brought forward. Making use of dynamic information gathered during the running of the target system for many times, use case model of the system can be incrementally constructed and presented in the form of UML use case diagram.
